Description

Technical Field

[0001] The utility model relates to the technical field of dust-free cotton swabs, in particular to a long-lasting anti-static dust-free cotton swab. Background Art

[0002] Cleanroom cotton swabs are designed specifically for cleanroom environments and are widely used in industries such as electronics, optics, and medicine, where high cleanliness is crucial. Unlike standard cotton swabs, they are manufactured using specialized materials and processes to prevent the release of dust and fibers. Cleanroom cotton swabs effectively clean small areas while reducing static electricity buildup. They are designed to provide greater cleaning precision and reliability.

[0003] A dust-free cotton swab disclosed in Chinese patent publication number CN202290614U is very convenient for cleaning circular deep holes. Since the hot-pressed edge is folded in half and located on the inside, secondary contamination caused by poor edge sealing and scratches on the product caused by the hot-pressed edge are avoided. The practicality is excellent, but the overall use effect of the dust-free cotton swab is not good, and it cannot effectively play a long-term anti-static role, which may cause contamination to sensitive equipment or surfaces, affecting the overall stability of the dust-free cotton swab. Utility Model Content

[0004] The purpose of the present invention is to provide a long-lasting anti-static dust-free cotton swab to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a long-lasting anti-static dust-free cotton swab, comprising a cotton swab rod, screw grooves are provided in the middle positions on both sides of the cotton swab rod, a first material layer is provided inside the cotton swab rod, the internal thread of the screw groove is connected to a screw rod, a cotton swab head is fixedly connected to one side of the screw rod, a second material layer is provided inside the cotton swab head, a protective shell is provided on the outside of the second material layer, and a handle is fixedly connected to the middle position of the top of the protective shell.

[0006] Preferably, the first material layer includes an inner core arranged in the middle position inside the cotton swab rod, and a protective layer is arranged on the outside of the inner core.

[0007] Preferably, the inner core is made of polycarbonate with an embedded antistatic additive, and the protective layer is made of thermoplastic polyurethane.

[0008] Preferably, the second material layer includes a cotton material layer arranged in the middle position inside the cotton swab head, the outside of the cotton material layer is provided with a nano coating, and the outside of the nano coating is provided with an antibacterial coating.

[0009] Preferably, the cotton material layer is made of high-purity dust-free cotton material, the nano coating is made of nano antistatic coating, and the antibacterial coating is made of silver ion coating.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This long-lasting anti-static dust-free cotton swab features a first material layer and a second material layer inside the cotton swab shaft and head, respectively. The first material layer on the cotton swab shaft has anti-static and antibacterial properties, while the second material layer on the cotton swab head utilizes a multi-layer composite material to ensure high cleanliness and excellent anti-static performance. This not only improves the performance of the dust-free cotton swab, but also eliminates static electricity accumulation and bacterial contamination on the outside of the cotton swab, ensuring the long-term stability of the dust-free cotton swab.

[0012] 2. This long-lasting anti-static dust-free cotton swab is equipped with a protective shell on the outside of the cotton swab head. The protective shell is made of silicone material, which is soft and elastic, can provide good protection, and is not easy to generate static electricity. A handle is provided on the top of the protective shell. The handle drives the protective shell to rotate, which can drive the cotton swab head and the screw to rotate. When the screw at the bottom of the cotton swab head is turned out from the screw groove on the cotton swab rod, the cotton swab head can be quickly replaced, so that cotton swab heads of different specifications and sizes can be replaced according to different usage scenarios, thereby improving the overall functionality and applicability of the dust-free cotton swab.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 , this utility model provides two technical solutions:

[0020] Embodiment 1, a long-lasting anti-static dust-free cotton swab, includes a cotton swab rod 1, a screw groove 101 is provided in the middle position on both sides of the cotton swab rod 1, a first material layer 2 is provided inside the cotton swab rod 1, the internal thread of the screw groove 101 is connected to a screw rod 3, a cotton swab head 4 is fixedly connected to one side of the screw rod 3, and a second material layer 5 is provided inside the cotton swab head 4.

[0021] The first material layer 2 includes an inner core 201 disposed in the middle of the cotton swab rod 1 , and a protective layer 202 is disposed on the outside of the inner core 201 .

[0022] The inner core 201 is made of polycarbonate with embedded antistatic additives, and the protective layer 202 is made of thermoplastic polyurethane to maintain the firmness and comfort of the rod.

[0023] The second material layer 5 includes a cotton material layer 501 provided in the middle of the cotton swab head 4 . A nano coating 502 is provided on the outside of the cotton material layer 501 . An antibacterial coating 503 is provided on the outside of the nano coating 502 .

[0024] The cotton layer 501 is made of high-purity dust-free cotton material to ensure low particle release and high cleanliness, ensuring the cleanliness requirements of the dust-free environment. The nano-coating 502 uses a nano-antistatic coating to effectively neutralize static electricity and reduce static electricity accumulation. The antibacterial coating 503 uses a silver ion coating to prevent bacterial growth and keep the cotton head clean.

[0025] The main difference between the second embodiment and the first embodiment is that:

[0026] A long-lasting anti-static dust-free cotton swab, the outer cover of the second material layer 5 is provided with a protective shell 6, and a handle 601 is fixedly connected to the middle position of the top of the protective shell 6.
